Question

place the right word or number combination in the right phrase. sound travels fastest through ___ sound is caused by ______ the range of frequency that can be detected by the human ear __ the loudness of the note increases as the _ of the wave increases. the pitch of a note increases as the ___ increases

Explanation:

To solve this, we recall concepts from Physics (Sound):

1. Sound travels fastest through → Solids (because particles in solids are closely packed, allowing faster vibration transfer).
2. Sound is caused by → Vibrations (of objects, which create sound waves).
3. The range of frequency that can be detected by the human ear → Audible range (typically 20 Hz to 20,000 Hz).
4. The loudness of the note increases as the → Amplitude (of the wave; amplitude relates to energy and perceived loudness).
5. The pitch of a note increases as the → Frequency (of the wave; higher frequency means higher pitch).

Filled Phrases:

• Sound travels fastest through $\boldsymbol{\text{solids}}$.
• Sound is caused by $\boldsymbol{\text{vibrations}}$.
• The range of frequency that can be detected by the human ear $\boldsymbol{\text{is the audible range (20 Hz–20,000 Hz)}}$.
• The loudness of the note increases as the $\boldsymbol{\text{amplitude}}$ of the wave increases.
• The pitch of a note increases as the $\boldsymbol{\text{frequency}}$ increases.
